Using Arrays In Php
Arrays are widely used, because of the lack of features in normal variables. That's why you can find arrays is most of the common programming languages. PHP also uses arrays in a very easy way. This tutorial will cover the basics of arrays.

Arrays and PHP: A Primer
For many years, arrays have been used to logically store and sequence data. They have also been the point of confusion for many developers. In this article, Tuna will talk about the structure of arrays and how you can create and manipulate arrays with the PHP scripting language.

PHP Arrays
When i first started learning PHP arrays confused me. I learned Perl first; arrays and variables in Perl are represented with different symbols. Not so in PHP, an array looks exactly the same as a variable, it starts with the dollar ($) sign.

Arrays
Arrays are sets of data which can be defined in a PHP Script. Arrays can contain other arrays inside of them without any problems (called a multidimensional array). Arrays can be referred to as tables, even temporary databases. Making an array is very simple, using the array function.

Introduction to Serializing
Serializing is a technique that allows you to turn variables, arrays, functions or objects from PHP into a form that can be used to store them, and when needed, convert them back into PHP. Serializing is useful for flatfile applications that store things in arrays, and are good for CMS features that can let you edit how it works to an advanced degree.

Welcome to PHP
This is a comprehensive article / tutorial on programming in PHP. It covers a variety of key topics including PHP Structure, Scalar Variables and Data, Data collection: Arrays, Operations and Comparisons, PHP Comparison Operators, PHP Logical Operators, Control Statements, The Function of Functions, and Object Orientation.

Working with Arrays
When simple variables are just not good enough, arrays come into play. The array section in the PHP manual, available at http://php.net/array, lists approximately 80 functions that are helpful. Therefore, this tutorial could be filled with array-related code alone. However, not all of these functions are really used often. Therefore, this tutorial presents the most important problems you'll have to solve when working with arraysand, of course, solutions for these problems.

Setting array keys and displaying the data
Arrays in PHP are variables which can hold more than one data item. Actually, they can hold many. This is useful if you need to hold a recordset or list of data, often needed in PHP scripts.

Using Type Juggling/Type Casting to Modify Data Types
We're going to be dealing with type juggling in this article. This is the process of instructing PHP how to handle the value after the type juggling. Type juggling can do absolutely all sorts, from converting integers to floats, arrays to objects, and even strings to binary as of PHP 5.2.1. It can also save you calling various functions and thus making your script quicker.

Using the Internal Array Pointers to Access Elements in Arrays
The native array pointer functions in PHP allow you to traverse an array without actually referring to specific array elements. They can be particularly useful if you're using an associative array and wish to use the first element in the array. An internal array pointer, in PHP, is fundamentally an invisible pointer that points to a particular record in an array.

Using arrays
Instead of having our information (variables or numbers) in variables like $Mydata1, $Mydata2, $Mydata3 etc, by using arrays our information may be contained in an unique variable. Very often, we will create an array from data obtained from a table with only one column.

Using Arrays (with EXPLODE)
Arrays are a collections of data, grouped into one variable, along a variety of streams. For example, I might have 6 names in one array, and to access the names I'll use $names[0], $names[1], etc. This function is often used with the FOR and FOREACH functions, but as this tutorial is written for beginners, I'll stick to using the WHILE() statement instead.

Type hinting with PHP
PHP has supported type hinting for parameter functions from version 5.0 for objects and from version 5.1 for arrays. Type hinting means the function specifies what type the parameter must be and if it is not of the correct type an error will occur. Type hinting is not supported for other types, e.g. for strings and integers.

Multidimensional Arrays
Array does not have to be a simple list of keys and values; each array element can contain another array as a value, which in turn can hold other arrays as well. In such a way you can create two-dimensional or three-dimensional array.

A HOWTO on Optimizing PHP
PHP is a very fast programming language, but there is more to optimizing PHP than just speed of code execution. In this chapter, we explain why optimizing PHP involves many factors which are not code related, and why tuning PHP requires an understanding of how PHP performs in relation to all the other subsystems on your server, and then identifying bottlenecks caused by these subsystems and fixing them. We also cover how to tune and optimize your PHP scripts so they run even faster.

Viewsource
A number of websites, including php.net, allow you to view the source code of their PHP pages. This is usually to allow you to see how the page is put together and how the PHP code itself is written. Usually, it is not possible to view the PHP source but with a built in function in PHP, you can.

Associative array with str_replace function
If you are a PHP developer, I'm sure you know the str_replace function for replacing strings and are probably aware that you can pass an array of strings as the search strings and an array as the replacements. What this post looks at is a way of using a single associative array instead of two arrays, which makes dealing with a large number of replacements much more maintainable in your code

Acquiring PHP MySQL
PHP and MySQL are already packaged in Linux and Mac OS X OSs. However, most PHP developer are actually using Windows when developing PHP applications. This is also true to myself. I have Mandrake Linux 10 but I'll just use it for testing purposes of my finished scripts. One reason is that Windows render an amazing web presence unlike any other OS's browsers. So this page will only cover the WAMP ( Windows, Apache, MySQL, PHP ). You will learn how to install Apache, PHP, and MySQL under Windows platform.
